Embodiment Construction

[0015] Regarding the features and implementation of the present invention, the preferred embodiments are described in detail below in conjunction with the drawings.

[0016] Please refer to figure 1 and figure 2 ,in, figure 1 It is a system block diagram of the present invention, and the system includes: a data storage module 130 , an image processing module 120 and a display module 110 .

[0017] figure 2 It is a schematic diagram of an electronic map displayed on the display screen 111 of the display module 110 of the present invention. After the user selects a first region to be queried through an input device (such as a touch screen, keyboard, mouse, etc.) and sets the first scale (such as 1:5000) 115 for displaying the first region, the image processing module 120 receives the signal input by the user, and reads the electronic map data of the first area from the data storage module 130 storing the electronic map data, according to the first scale 115 and the electro...

Abstract

The invention discloses an electronic map display system and a method thereof, which display an electronic map of different proportional scales in multiple windows; the electronic map display system comprises a data memory module, an image processing module and a display module; the invention adopts multiple windows to display the electronic map of different proportional scales and marks the relative position of the electronic map of the high proportional scale in the windows displaying the electronic map of the low proportional scale, thereby facilitating the inquiry of users.

Description

technical field [0001] The present invention relates to an image processing system and its method, in particular to an electronic map display system and its method. Background technique [0002] At present, with the rapid development and popularization of computer and network technology, electronic maps are gradually recognized by people. Electronic map is a new map service method realized by using network technology, communication technology and geographic information technology (Geographic Information System, GIS). Electronic maps are widely used in car navigation, personal navigation and GPS navigation and other fields. [0003] However, due to the size of the display screen, the electronic map display method of the known technology cannot allow users to quickly understand that their location is located in a larger area (such as districts, cities, provinces, etc.) like a traditional map with full drawing size. relative position. At the same time, the user cannot know t...
